This invention relates to the journal and journal box such as are used in railroading; and has for its main object vto provide an arrangement which will prevent waste which is in the journal box from being thrown up beneath the brass through which the box is supported on the journal.

Another object of the invention is to utilize any movement of the brass for operating a device to close any gap which may exist between the journal and its bearing so as to prevent any waste from being thrown into said opening to lodge under the brass.

Another object of the invention is to prevent a continual contact of the preventer device with the journal as it rotates, leaving the same normally free for such rotation and to contact the journal and close any passage to the lifting of waste only when abnormal conditions occur in the journal box and journal such for instance as when the cai` is stopped by bumping or started by excessive jerking pulls or by moving around sharp corners.

With these and other objects in View, the invention consists of certain novel features of construction,l as will be more fully described, and particularly pointed out in the appended claims.

In railroading, as the weight oi cars and the power to move them increase, it often occurs that waste is thrown up beneath the brass of the journal box which causes excessive friction and heating of the bearing. The lodging of the waste up under the brass of the bearing is believed `to be caused at the time when some shock occurs, such for instance as by the freight car in the freight yard being allowed to roll from the hump toward other cars which are stationary and alv lowed to bump the other cars in order that it come to rest. The speed which such a rolling freight car attains is often eight to ten miles an hour when such bump and shock occurs, and when such shock occurs the body of the car can be seen to raise, thus relieving any pressure upon the brass through which the weight. of the car is supported and allowing this brass to shift its position on the journal or even lift with reference thereto. Also, when `a heavy train starts by successively taking up the slack which occurs between the draw bars of different cars each time `it disturbs the oil film for lubricating the journal in its bearing; and in order to permit this oil to maintain its lubricating nlm undisturbed by contacts with any parts of the journal, l have provided a device for preventing the flying or" waste beneath the brass by reason of its movement; and I cause the movement of the brass to actuate the device and move it into contact with the journal so that there will be no opening permitted between the journal and the brass to permit the waste from ying up and lodging beneath the brass, thus, the device ordinarily allows free running of the journal in its bearing and also blocks the entranceof any waste beneath the brass; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawings, It designatesr the journal upon which the Wheels of a car, such as a freight car, are Vi'lxed so as to turn with the wheels as they roll along the tracks, and l l designates generally the journal box which ls attached to the truck of the car 'and through which Weight is applied to the journal. This journal box consists of a casing l2 having a saddle piece I3 and brass I4 of an upper frustro pyramidal shape tting in a similarly shaped recess I5 in the saddle with babbitting material I1 located in the brass I4 which contact with the journal I0. The lower part of the casing contains waste I8 which is maintained saturated with some lubricant which causes a film of the lubricant to be disposed over the surface of the journal and lubricate the journal in its contact with the babbitting material in the brass.

When the casing is subjected to severe shocks or sharp turns or some such action it often occurs that the car tends to raise from the journal I0 under such conditions, there being shown in Fig. 2 a relation of the parts when such conditions occur; and in this case when the saddle I3 and casing I2 lift there is an opportunity for the brass I4 which is then loose within the saddle I5 to shift its position and at the same time lifting, as illustrated in Fig. 2, and at such times under such shocks the waste will jump up and under some conditions will enter the space 20 between the journal and the brass I4 which will cause heating of the bearing and detrimental action thereto; and in order to prevent this jump-ing upwardly of the waste I have provided a plate 2| which is secured through openings 22 by means oi bolts 23 to the sides of the casing I2. I'he uper portion of the plate ZI is inclined inwardly as at 2li to provide an arm which is bent over as at 25 to provide a journal engaging edge 26 which is scalloped or provided with projecting portions 2l and recesses 28. The material is of a resilient or elastically bendable character with the convex rolled curved portion 25 in a location to contact with the edges 48 of the brass I4 so that should the brass shift its position relative to the journal I0, such as shown in Fig. 2, the edge i8 of the brass will force the inwardly inclined portion 2li, 25 and 25 of the guard inwardly so that the edges 2l, 28 will contact with the journal, such as shown at the left in Fig. 2 and thus prevent any waste as at 29 from jumping up between the journal and the brass to become lodged therein as soon as the weight of the car causes the brass to move back into its normal position, such as shown in Fig. l.

In some instances instead of utilizing the simple form of guard shown in Figs. 1, 2 and 3 I may7 provide a double acting guard such as shown in Figs, 4 to l0 inclusive. In this instance a bracket 3% is provided with openings 3I through which bolts 32 extend to secure the same to the casing l2. This bracket supports a pivot pin 33 upon which a unit 35 is pivotally mounted, this unit having a downwardly extending arm 36 and an upwardly extending arm 35 with a hookshaped portion 3l suitably secured to the upper portion of the arm by means of a bolt 38. These arms are separate but both are mounted adjacent to each other on pivot pin 33. The lower arm 33 is provided with a projection or stop member 36 which extends above the pivot pin 33 and in posi- `tion to engage a. portion of the upper arm 35 and a coil spring 33 extends about this pivot and has portions engaging the arms to urge them to swing towards each other against the stop 33 so they will move about the pivot as a unit, although under certain conditions one will move with reference to the other. The edge of the lower portion ci the arm 36 is scallop-shaped or provided with projections 39 and recesses 40 and the engaging edge of the hook 3l `is similarly shaped with projections di and recesses 42 both for suitable engagement with the journal IU upon certain relative movements of the journal and bearing. A coil spring 43 extends about the pivot pin 33 with one end portion 44 engaging the upper portion of the arm 35 while the other end portion 45 engages the bracket 3&3 so as to tend to swing the unit 35 about its pivot with its upper end knuckle 46 engaging the lower edge 41 of the brass. This arrangement is provided on opposite sides of the journal and box with the parts relatively formed in opposite directions.

Should a shifting of the brass occur, as shown in Fig. 2, the portion 41 of the brass in Fig. 4 will act against the knuckle I6 of the guard to swing the same as a unit about its pivot so as to cause the lower portion 36 of the arm to contact the journal and provide a pocket between the lower portion of the arm and the bracket 30 to prevent the jumping of waste upwardly to lodge in the opening 20 between the brass and the journal. The upper arm 35' being movable away from engagement with the stop l5 should movement of the brass continue after the arm 36 contacted the journal, while at the same time the spring acting about the pivot on the opposite guard would cause its edge lil, 42 to engage the journal and effectively prevent any movement of the waste upwardly into a location between the brass and the journal on this side of the journal, whereby an eilective means is provided on both sides of the journal box for preventing the jumping of the waste upwardly into a location where the bearing occurs.

By these arrangements the waste is prevented from jumping up under the brass while at times of normal running there is no contact of the device with the journal.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege or" resorting to all the mechanical changes to which the device is susceptible, the invention being deined and limited only by the terms of the appended claims.
